ROTARY BRUSH.

Specification of Letters Patent.

Patented Jan. 16, 1917.

Application filed October 22, 1915. Serial No. 57,294.

To all whom it may concern:

Be it known that I, WAoLAw Knns'rowioz, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Rotary Brushes, of whichthe following is a specification.

This invention relates to rotary brushes which are operated by a motor,and its object is to provide a novel and improved brush of this kindwhich is so mounted and supported that it may be used in variouspositions, and easily handled and controlled.

The object stated is attained by means of a combination and arrangementof parts to be hereinafter described and claimed, and in order that thesame may be better understood, reference is had to the accompanyingdrawings, in whichv Figure 1 is a side elevation of the invention partlyin section; Fig. 2 is a partly broken away; Figs. 3, a and 5 aresectional views on the lines 33, 4l-l and 5-5, respectively, of Fig. 2,and Fig. 6 is a perspective view of a wiper which may be substituted forthe brush.

Referring specifically to the drawings, 10 denotes a suitablyconstructed casing carrying the brush and the motor for operating thesame, and provided with a handle composed of separable sections 11suitably connected so that the handle may be lengthened or shortenedaccording to the height and location of the surface to be operated on.If the brush is used for ceiling work, the handle is insertedtelescopically into a bottom piece 12 mounted on a caster wheel 13, sothat the device may be wheel-supported while in operation. A set screw14 secures the handle to the bottom piece 12.

The casing 10 is trough-shaped and constructed of sheet metal, and it ispivotally supported between the branches 15 of a fork, the stem 16 ofwhich latter is connected to the top one of the handle sections 11. Theconnection is made by a sleeve 17 secured to the top handle section,into which sleeve the fork stem extends, with a spring 18 interposedbetween the opposite ends of the-handle section and the fork stem. Thefork stem and the fork branches are separably connected as shown in Fig.5 (an ordinary screw joint being employed). A head 19 on the lower endof the fork stem prevents withdrawal from the sleeve 17.

The casing 10 has pivots 20 at its ends for plan view,

connection to the fork branches 15, so that it may be swung to place thebrush in various positions according to the location of the surface tobe operated on. Fig. 1 shows in full lines the casing adjusted to locatethe brush at the top, so that a ceiling may be operated on, and indotted lines the casing is shown tilted forward to bring the brush tothe side for operating on a wall. For locking the casing to the fork,the branches of the latter have curved arms 21 provided with slots 22through which pass bolts 23 fast on the end walls of the casing andcarrying wing nuts 24.

Adjacent to the end walls of the casing 10, the latter contains atransverse partition 25, dividing the easing into two compartments, onewide and the other narrow, the latter being next to the last mentionedend wall of the casing. The wide compartment is closed at the top forabout one half of its width, the cover 26 being preferably integral withthe side wall of the casing. The narrow compartment is provided with ahinged lid 27 held closed by an ordinary spring catch 28.

In the narrow compartment is housed a spring motor, the spring of whichis indicated at 29. This spring, through a train 30 of gears operates ashaft 31 which actuates a cylindrical brush 32. The bristles of thebrush are mounted on a wooden core 33 having at one end a centralaperture 3a which is squared to receive the squared end of the shaft 31.The partition 25 has an opening 35 through which the shaft 31 passes.The opposite end of the core 33 has a short spindle 36 seating in abearing 37 on the adjacent end wall of the casing 10. The bearing 37 hasa hinged cover 38 to permit removal of the brush, and a latch pin 39looks the lid in closed position. To remove the brush, the pin 39 istaken out, and the brush is shifted endwise until the end of the shaft31 is clear of the aperture 34:, after which the brush can be lifted outof the easing upon swinging the bearing cover 38 open. A reversal ofthis operation positions the brush in the casing and couples it to theshaft 31. The pin 39 extends across the end of the spindle 36 and thuslocks the brush against endwise movement in this direction, therebypreventing the brush from being uncoupled from the shaft 31.

The spring motor hereinbefore described drives the brush 32 when thesame is coupled to the shaft 31, and in order to control the equalfacility.

The compartment of the casing 10 in which the brush 32 is mounted willbe partly filled with water, as shown in Fig. 4, in which thebrush isimmersed, an overflow spout 42 being provided to maintain a properlevel. This spout maintains such a water level in the casing, that whenthe latter is tilted to the dotted line position in Fig. 1 the waterlevel will not be above the opening in the compartment through which thebrush projects. The brush projects a suflicient distance so that it maycome in contact with the surface to be operated on. A rubber wiper orsqueegee shown at 43 in Fig. 6 may be substituted for the brush 32, forwiping the ceiling or walls dry, the water in the brush compartment ofthe casing 10 being first run out.

The brush may be used for cleaning, as well as for coating walls andceilings, and it is easily handled and controlled. The spring 18provides a cushioned support for the brush and holds the same pressedagainst the surface being operated on.

The opening 44 in the'top 26 of the casing 10 through which the brush 32projects has opposite outstanding guard flanges 4E5 a rubber wiper strip46 which may be used for wiping off any excess liquid from the surfaceto be cleaned or coated.

I claim 2+ The combination of a handle, an elongated receptacle carriedby the outer end of the handle and adjustable angularly with re spectthereto, a. rotary'brush mounted in the receptacle at one end thereof,the top of the receptacle being closed throughouta substantial portionof its length, leaving a 5 top openin at the end of the receptaclecarrying the brush, said brush being located partly beneath the top ofthe receptacle, the

depth of the receptacle being less than. the

diameter of the brush, and the working per- 55 tion of the brushprojecting through the aforesaid top opening.

In testimony whereof I afiix my signature.
